In the connected state, the flanges, the bellows, and the heat-receiving plate are abutted and circumferential seam welded.
本発明は、プリント仮に実装される集積回路素子を強制
水冷する冷却装置において、ベローズ部分の）容接時の
組立方法に関する。The present invention relates to a method for assembling a bellows portion in a cooling device for forced water cooling of an integrated circuit element temporarily mounted on a print.

特性等の違いによりそれぞれ単品で製造され、これら３
者が冷媒の洩れを生じないように密閉した状態に溶接し
て組立てられる。In this type of cooling device, a bellows is installed below a cold plate through which a refrigerant passes through a flange so as to communicate with a refrigerant passage. It is also known that the heat receiving plate at the bottom of the bellows is brought into close contact with the element while absorbing variations in the height of the element through expansion and contraction of the bellows, and forced water cooling is carried out by removing heat from the element with a refrigerant. Here, each part of the bellows, flange, and heat receiving plate used in the above cooling device is made of materials,
Each is manufactured individually due to differences in characteristics, etc., and these three
The refrigerant is assembled by welding in a sealed state to prevent refrigerant leakage.
そこで、従来上記ベローズ部分の溶接組立ては第２図の

。フランジ２は中心に孔３を有して一端に鍔部２ａが突
設され、受熱板４は中実板状であってその一端に鍔部４
ａが突設される。Therefore, conventionally, the bellows portion is welded and assembled as shown in FIG. That is, the bellows I is a bellows-like expandable and retractable cylindrical body, and has flanges 1a and lb protruding from both ends. The flange 2 has a hole 3 in the center and a flange 2a protruding from one end, and the heat receiving plate 4 has a solid plate shape and has a flange 4 at one end.
A is provided protrudingly.
ここで、ベローズ１とフランジ２は中空であるが、受熱
板４は中実であるため、溶接組立時に溶接治具１０とし

を突き合わせる。この状態で全体を回転しながら鍔部１
ａと２８．１ｂと４ａの２ケ所の円周を電子ビーム溶接
し、溶接ビードＡにより液密に連結して組立てられる。Here, since the bellows 1 and the flange 2 are hollow, but the heat receiving plate 4 is solid, a support shaft 11 and a chuck 13 attached to one end of the shaft 12 are used as the welding jig 10 during welding assembly. And the support shaft II has a flange 2.
The heat receiving plate 4 is fixed to the chuck 13 coaxially with the bellows I, and the flanges 2, bellows L and heat receiving plate 4 are pressed, and the flanges 1a and 2a, 1b and 4a are
match. While rotating the whole body in this state, flange 1
Electron beam welding is performed on the circumferences at two locations, a, 28.1b and 4a, and the weld beads A are used to connect them in a liquid-tight manner.
ところで、上記従来例のものにあっては、ベローズ１と

又は１２の軸受は等のガタにより芯ズレを生じ、これを
修正できない。このため、特にベローズ１と受熱板４の
鍔部１ｂと４ａの溶接の確実性に欠ける問題がある。By the way, in the conventional example described above, since the bellows 1 and the flange 2 are supported by the same support shaft 11, centering is ensured. However, since these and the heat receiving plate 4 of the chuck 13 abut against each other in a completely separated state, the shaft 11
Or, the bearing 12 may be misaligned due to play, and this cannot be corrected. Therefore, there is a problem in that the welding between the bellows 1 and the flange portions 1b and 4a of the heat receiving plate 4 is not reliable.
本発明は、かかる問題点に鑑みなされたもので、その目

装置の組立方法を提供することにある。The present invention was made in view of such problems, and its purpose is to provide a method for assembling a cooling device that can ensure the centering of flanges, bellows, and heat receiving plates and reduce welding defects. There is a particular thing.

される受熱板と対向する点に着目し、支持軸先端と受熱
板の中心に突起と穴の芯出し手段を保合可能に設ける。In order to achieve the above object, the assembly method of the present invention focuses on the point where the tip of the support shaft that supports the flange and bellows faces the heat receiving plate fixed to the chuck, and a protrusion is formed between the tip of the support shaft and the center of the heat receiving plate. and hole centering means are provided so that they can be aligned.
そして、支持軸と受熱板の中心を芯出し手段により直接
